Study takes close look at how teens and young adults share secrets

A new study found that teens and young adults share similar secrets regardless of their family structure, with no significant differences between single-parent, blended, and original families. The study suggests that keeping secrets is a normal part of growing up and doesn't imply dysfunction in stepfamilies.

Mayo Clinic study shows suicide rates overstated in people with depression

A Mayo Clinic study challenges the long-held notion that people with depression are at a higher risk of suicide. The research found a stair-step hierarchy of suicide prevalence based on treatment history, with hospitalized patients being at the highest risk level. This new understanding aims to minimize hysteria surrounding depression ...
